The invention relates generally to anchor plates, and more particularlyto anchor plates for holding the ends of steel strapping or the like.

It is common practice in loading box cars to employ steel strappingwhere possible to bind the load or portions of it together, and it iscommon practice to anchor the ends of such strapping to the sides or thebottom of the car to brace the load, as well as prevent undue shiftingthereof. If plates or other means are employed and fastened to the carby means of nails or other similar means, it is generally necessary topry the nails out to release the anchor plate, and oftentimes duringsuch operation the sides or bottom of the car are damaged due tosplitting of the wood, etc.

The present invention has among its objects the production of an anchorplate for fastening the ends of the steel strapping to a supportingsurface by means of nails, drive screws or the like, in which it isunnecessary to remove the mounting nails or other means to release theplate and strap end during removal thereof, whereby the mounting maythen be driven flush with the wall or other surface, thus eliminatingthe possibility of injury to the same.

A further object of the invention is the production of such a platewhich is so designed that it may be readily engaged with a hammer or thelike to facilitate the disconnection thereof from the mounting means.

A further object of the invention is the production of such a platewhich is so constructed that, if desired, it may be locked in positionuntil the time of disconnection, and readily unlocked when desired.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts:

Fig. l is a plan view of an anchor plate embodying the presentinvention;

Fig. 2 is a side elevation of the plate illustrated in Fig. 1;

Fig. 3 is a plan view of a mounted plate and strap end; and

Fig. 4 is a sectional view taken approximately on the line 4-4 of Fig.3.

2 Claims. (01. 24-222):

Referring to the drawings, and more particularly to Fig. 1, theembodiment of the invention illustrated comprises a substantiallyrectangular plate indicated generally by the numeral l .of suitablematerial, having an elongated rectangularly shaped slot 2 therein, of asize to receive'the particular strapping material to be employed. Theplate is provided with a plurality of openings 3 which, in-the presentembodiment of the invention, are illustrated as of more or less keyholeshape, each having a small'. narrow elongated portion 4 and an enlargedgenerally circular portion'5, the portions 4and 5 being correspondinglypositioned so that the portions 4 extend towards one end-of the plate,and the portions 5 towards the opposite end of the plate; .The widthoftlie narrow portions 4 of the openings '3'is slightly larger thantheshank diameter of'the mounting hall or other means to be employed,,whilethe portions 5 are of sufficient size to permit thehead of themounting means to pass therethrough. It will be apparent that therelative dimensions and proportions of the openings 3 will depend uponthe size of the mounting means employed. 7 As illustrated in Fig. 2,the-ends 6 and 1 of the plate are provided with outwardly extendingflange portions 8 and 9 respectively, the fianget being of suflicientheight to act as an abutment which may be struck by a hammer or the liketo slide the plate along the supporting surface.

Referring to Figs. 3 and 4, the anchor plate illustrated may be utilizedin the following manner:

The ends of the band or strapping S is bent back upon itself and thefree end inserted in the slot 2, thereby hooking the strap on one edgeof the plate, following which, the plate is rolled over a half turn topartially wind the strap about the plate, after which it is placed inposition on the mounting surface and nails N positioned in the portions4 of the openings 3 and driven down so that the heads H of the nailsengage the upper face of the plate adjacent the portion 4 of the opening3. The nails are so located that when all of the same have been driven,they will be at the end of the narrow portions 4 of the respectiveopenings. If it is desired to provide additional means for preventingshifting of the plate I, a nail may be driven into the supportingsurface as indicated at A, so that the head of the nail will bepositioned below the upper edge of the flange 9 and abut the end 1 ofthe plate, thus preventing a movement of the plate relative to the nailspositioned in the narrow portions 4 of the openings 3.

When it is desired to remove the plate, it is merely necessary to drivethe nail A flush with bring the heads of the nails flush ,with themounting surface. It will be apparent that no damage will be done to thesupporting surface by driving the nails flush therewith, and that if itis desired to withdraw the nails, this may be 7 accomplished withconsiderably less difiiculty than if the nails had tobe pryed 01f at thetime of removal of the anchor, plate.

' .n will likewise be apparent tha by providing the flange 9, the nailAwill firmly abut the end of the plate, thus securely holding the same inposition. V V l It will likewise be apparent that as the plate may beremoved without damage, it may readily be re-employedv for. the purposesintended.

Having thus described my invention, it is ob-i vious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention; hence, I do not wish to be understoodaslimiting myself to the'exact form, construction, arrangement andvcombination of parts .hereinshown and described or uses mentioned.v

What I claim as new Letters Patent is: I: V

1. In an anchor plate. forstrapping, the combination of a flat platemember having an elongated slot therein for receiving the free end of aband to be engaged with said plate, said plate having a plurality ofrelatively narrow openings therethrough extending in the same directionas said slot, and adapted to receive and engage mounting means formounting said plate on a and desire to secure by supporting surface,said openings each terminat ing at one of their corresponding ends in arelatively large portion of a size to permit free pas-- sagetherethrough of the respective mounting means, said plate having anoutwardly raised portion at the end thereof adjacent the relativelylarge portionsof said openings to provide a toolengageable abutment, andprovided with an outwardly raised portion at the opposite end of said:plate adapted to be engaged by means secured to such supporting meansfor preventing said plate from shifting relative to mounting meanspositioned in the narrow portions of said openings.

2. In an anchor plate for strapping, the com-' bination of a fiat platemember having an elon gated 51st therein for receiving the free end of aband to be engaged with said plate, said plate having a plurality ofrelatively narrow openings therethrough extending in the same directionas said slot, and adapted to receive and engage mounting means formounting said plate to a supporting surface, said openings eachterminating at one of their corresponding ends in a relatively largeopening of a size to permit free passage therethrough of the respectivemounting means when aligned with the respective relatively largeopenings, said plate having an outwardly raised portion at the endthereof adjacent the relatively large openings for'engagement with asuitable tool and provided with an outwardly raised portion at theopposite end of saidplate adapted to engagemeans for retaining saidplate in mounted position on such mounting means.
